Banksy Sprays Brooklyn

…or does he?
I walked by what looks like another Banksy stencil that got put up in my hood recently (Roebling St. Williamsburg Brooklyn). I’ve seen a couple of Banksy-esque looking pieces around lately (there was a soccer player on driggs a couple months ago, and a narrow piece on N6th) but I was never sold that they were really put up by Banksy. Turns out that this latest piece was done by an artist named Nick Walker. His work is very close (in content and style) to what Banksy does.
Could be the reason Banksy is so big. So many people have a similar style, and want to be anonymous… it would be easy for most people to just attribute the work to the only big name they know: Banksy.
